Water cooling connection
Characteristics
of water cooling
In order to limit the corrosion and clogging of the cooling pipes,
it is recommended to use cooling water with the following
characteristics:
- Treated soft water or non-corrosive industrial water
- Solid particle size (maxi): 0.2 mm
- Hardness < 7 milli-equivalent/l
= 350 mg/l of CaCO
3
(calcium carbonate)
= 35° f (French degree)
- pH between 7.5 and 11
- Resistivity 1 500
.cm < R < 20 000
.cm
- Temperature: 15 °C < T < 40 °C
- Pressure range between 200 and 700 hPa
- Flow rate: 60 l/h
- Deionized water compatible
Do not mount water fittings above electrical components in case of leak
at water fitting connection.
In case of water temperature is < 20 °C, there is a risk of condensation.
The use of uncontrolled city water can lead to water circuit clogging due
to limestone deposition, which may necessitate in the worst case a complete
cleaning and overhaul of the cooling circuit.
The presence of micro-organisms like aquatic weed and micro-biological
substances like bacteria can lead to cooling problem in the pump. Appropriate
water treatment system need to be used to prevent growth of such micro-
organisms.
Water leak risk : maintain the water valve inlet fitting with a flat
wrench (13 mm) during the water line connection (pipe equipped with
connector), this to avoid valve damage.
Filtering connection
on a brass block
Clean the male and female fittings: remove dust or traces of thread
sealant.
Apply a pipe thread sealant on the male fitting (Teflon™ tape or
chemical sealant product by Loctite™ for example), insert the fitting
by hand.
While holding fitting body steady with a wrench, tighten the fitting
with a second wrench.
Check that there are no leaks.
